A doctor knows from experience that 10% of the patients to whom she gives a certain drug will have undesirable side effects. Among the 13 patients to whom she gives the drug, find the following probabilities. (Give your answers correct to three decimal places.)
(a) Find the probability P(At most two will have
undesirable side effects).
(b) Find the probability P(At least two will have
undesirable side effects).[Hint: apply complement rule, P(at least
2) = 1 - p(less than 2) = 1 - [P(0) + P(1)]
Check if a binomial probability distribution applies or not.

A medical doctor has a data set about her patients. From her past data, she knows that she will have 80% follow-up visits after her first contact with her patients (a) If she has 10 patients today, what is the probability that the follow-up patients will be exactly 6? (b) Now consider 60 patients, then what is the probability that she will have at least 50 follow-up patients? (use the central limit theorem) (c) Out of 60 patients, what is...

Approximately 8.26% of patients in the Seasonal Effect data set contracted an SSI. If this happens completely randomly, in a random selection of 10, calculate the following probabilities, from a binomial distribution with parameters n=10 and p=0.0826. Show all work. Identify the complement of {X≥1} and use the rule of complements to calculate the probability that at least 1 patient contracts an SSI, P(X≥1) (10%) probability that more than 1 but less than 5 patients contract an SSI, P(1<X<5) (10%)...

Kelly is contemplating on returning to graduate school to earn her MBA. She knows from experience, that she can get a well paying job after undergraduate school. The probability of getting a job with a salary of $20,000/year is 75% and a job with a salary of $30,000/year is 25%. However, if she chooses to attend and finish graduate school, her salary would likely increase. The probability of getting a job with a salary of $40,000/year is 75% and getting...
